From the computer to the tabletop, this is all about games. Updated each week-end.
I saw this one on YouTube just in time: Midwinter Minis is holding a one-week painting competition
The full details are on their video, but you need to take a picture of your unpainted mini this week-end, and then post a picture of the same mini painted next week-end to enter.
When the timing works out, these short challenges can provide the boost needed to complete some long-neglected figures, or even some newly-bought figures!
